Application filed April 14, 1927. Serial No. 183,847

This invention relates to filling replenishing looms and more particularly to the bobbin cleaner attachments of such looms, whereby the discharged filling carrier is cleaned of waste yarn thereon during'the loom operation.

' In that type of filling replenishing looms whereinthe filling carrier or bobbin in the shuttle is changed toeffect replenishment, there remains upon the ejected filling carrier or bobbin an amount of waste yarn which must be removed before the filling carrier or bobbin can be again supplied with filling. It is important, therefore, that each of the filling carriers or bobbins ejected from the shuttle during replenishment shall have the waste yarn cleaned therefrom, and to insure that successive filling carriers or bobbins ejected from the shuttle shall not pass from the bobbin cleaning attachment prior to being cleaned, the present invention provides means for holding the bobbin in bobbin cleaning position with its upwardlyextending filling in contact with the bobbin cleaner and on replenishment of filling to trip the bobbin holding means for the discharge of the cleaned filling carrier and then quickly return the same'to its initial position that the incoming filling. carrier to be cleaned shall be arrested in bobbin cleaning position and not be permitted to pass from" the bobbin cleaning attachment until it has been cleaned. To effectively carry out the purposes of the invention, a tripping device is provided for the bobbin holding means and provision is made foradjusting the tripping device so that the bobbin holding means-will release the cleaned filling carrier during a part of the replenishing operation and permit the bobbin holding means to return to its bobbin holding position before the comple tion of the replenishing operation, with the result that the incoming fillingcarrier to be cleaned will be arrested for the operationof the cleaning device.

The invention and new combination of parts and novel features thereof will best be made clear from the following description and the accompanying drawings of one good form of the invention.

In the drawings: 7

Fig. 1 is a perspective view with some of the parts broken away, showing a filling replenishing loom with the present invention associated'therewith; i' i Fig. 2 is a perspective view with parts broken away, showing the action of. the trip ping devicefon replenishment of filling;

Fig. 3Zis a sectional detail longitudinally through the bobbin cleaner and its assoc'iated parts; and F Fig. 4: is a section on the line H of The loom frame 1 may be of usual construction and mounted on the breast beam 2 is the magazine or hopper stand 3, the rotary portion of which carries a number "0'1 filling carriers 4 which are successively moved to filling replenishing position. EX tending from the hopper stand 3 is the pin or stud shaft 5 on which is mounted the transferrer 6 having its downwardly extending arm 7 connected with a dogf8 adapted to be engaged by a hunter on the lay to effect replenishment of filling. These parts are or may be of usual character and need no further explanation as they are now well understood in the art.

Secured to the 100m frame 1 is the bracket 9 which supports the bobbin receiver 10 which has an open bottom 11, and below the bottom of the receiver is the bobbin can 12 into which the cleaned bobbins are discharged.

Extending transversely through the bobbin receiverlO is the cleaning shaft 13,011

one end portion of which'is a pulley 14 which maybe driven by a belt 15 actuated by some going part of the loom, as, for instance, the lower or cam shaft 16. In'the present instance, the cam shaft 16 is provided with the pick cam 17 and on the hub of the latter is the pulley 18 about which the belt 15 passes and by which the bobbin cleaner rotated during loom operation. Mounted on the bobbin cleaner shaft 13 is the bobbin cleaner 19} provided with a roughened surface which may be formed as a series of pins 20 for withdrawing or unwinding the upwardly extending portion a of the filling from the bobbinQLwhich is' supported below'the bobbin cleaner for this purpose.

The bobbin positioning means'comprises a bobbin support22 which is secured. to a shaft 23 extending transversely of the bob-' bin-receiver, and a spring 24 normally acts upon the bobbin support 22 to maintain it in its raised or bobbin supporting position. The bobbin support 22 is preferably inclined below the bobbin cleaner and its lower end portion cooperates with a stop which limits the upward swinging movement of the bobbin support 22 under the actuation of its closing spring 24:- Tn the present instance of the invention, the stop comprises a downwardly inclined bobbin de-- flector 25, and lower end portion of which is connected by a projection 26 with the bobbin receiver, and the lower end portion of the bobbin support 22 is adapted to ongage the projection 26 or lower edge of the bobbin deflector to normally close the space between them and maintain the bobbin, as 21, Fig. 1, in bobbin cleaning position.

Above the bobbin support 22 is the bobbin stop 27 against which the incoming bobbin may contact when it is ejected from the shuttle. The bobbin stop 27 may be variously contrived, but in the present case it is formed of canvas and at its lower end is supported by a rod 28 extending transversely of the bobbin receiver 10, and at its upper end is similarly supported by a rod 29, each of which rodsmay appropriately engage a loop formed in the canvas at each end.

The rod 23 to which the bobbin support 22 is securedextends through a side of the bobbin receiver 10 and is provided on the bobbin support to its initial position before outer end thereof with a crank arm .30, the upper end portion of the arm 30 being provided with the outwardly extending portion 31.

I The transverse or change shaft 32 is mounted on the front portion of the breast beam, as usual in filling replenishinglooms, and hassecured thereto the downwardly extending arm 33 to which is adjustably connected at its lower end the trip arm 3st,.

port 22 in a downward direction to discharge the cleaned filling carrier previously supported thereby. On continued operation of the replenishing mechanism, the arm 36 moves frontwardly and is freed from the arm 31 of the bobbin support prior to the completion of the replenishing operation, the effect being that the spring 2 will close the the incoming filling carrier or bobbin reaches the bobbin support and thereby arrests the incoming bobbin to be cleaned in bobbin cleaning position.

The trip mechanism for the bobbin sup port acts first to discharge a cleaned filling carrier, and before the replenishing operation iscompleted'the trip mechanism frees the bobbin support to the action of its spring 24, so that it closes before the incoming filling carrier arrives in bobbin cleaning position. In Fig. 2 the incoming nllmg carpermit the bobbin support 22 to move into contact with the bobbin deflector and close the ezkit or discharge passage.

In order that the desired action may be accomplished, the trip arm 34: is adjustably secured to the arm 33, so that the timing can be regulated to effect the interception of the incoming bobbin before it reaches bobbin cleaning position.

, As hereinbefore stated, the bobbin cleaner 19 is mounted on the shaft 13 and is secured to said shaft by a yielding clutch connection which may be disengaged by endwise movement of the' bobbin cleaner. The clutch comprises a series of fingers 37, Fig. 3, about which passes a contractile spring 38, and the end portion 39 of the bobbin cleaner is formed to engage between the spring actuated arms 3'? by pushing endwise upon the bobbin cleaner, and, conversely, the bobbin cleaner may be removed from the shaft 13 endwise by a reverse pull upon the bobbin'cleaner. I

Secnred'to the bearing t5 of the shaft 13 is a clutch guard 40, Fig.3, which extends through the side wall of the bobbin cleaner and overlies the clutch, thereby preventing yarn from being wound upon the clutch or interfering with its. proper operation as hereinbefore described. The guard 40 may be appropriately secured to the bearing 4-5 by a set screw i1 which passes through the pub portion of the guard, as indicated in The opposite side wall of the bobbin receiver is provided with an opening 42 which is normally closed by the flange 43 on the guard 44 which encircles the outer end portion of the bobbin cleaner. By endwise removal of the guard 44:, the bobbin cleaner 19 may be removed endwise from its clutch connection with the shaft 13 and permit the yarn which has been wound thereon to be stripped from the bobbin cleaner.

The trip mechanism for the bobbin support 22 affords a simple and effective means for impulsively opening the bobbin support for the discharge of a cleaned filling carrier andpermits its closure prior to the completion of the replenishingoperation to thereby intercept and insure that the incoming filling carrier shall not pass from the bobbin cleaning attachment before it has been cleaned.
